Horse-drawn icebreaking vessels had been used in the Netherlands as far back as the 17th century to open up frozen canals in order to prevent dike breaks and floods; however, until the 1890s, the Rijkswaterstaat (Department of Waterways and Public Works) had always hired icebreakers from private firms or individuals. The decision to build government-owned icebreakers in the 1890s was driven by cost considerations, as icebreaking became an increasingly important responsibility of the government.
Following success with the 1894-built icebreaker Achilles, the Rijkswaterstaat released a tender to 15 shipyards requesting bids for a 'propeller-driven steamship for breaking river ice'. The winning bid of 49,400 guilders was submitted by Frederik Meursing of the Amsterdam shipyard De Nachtegaal (The Nightingale). Meursing had also guaranteed the lowest coal consumption per horsepower. Perhaps as a result of never having built an icebreaker before, Meursing's costs soared and he incurred a loss of 12,000 guilders on the project in the end. As completed, the vessel had a raised bow, a draught at the front of only 20 centimetres, and a stern designed to channel ice away from the ship's propeller. Additionally, reservoirs at the fore and aft peaks of the vessel could be filled with water to trim the ship, with the reservoirs heated by a steam pipe to keep the water inside them from freezing. Given the shift from iron to steel in shipbuilding in the late 19th century, parts of the new icebreaker were made of Siemens-Martin steel up to 13 millimetres thick, while the rest of the ship was constructed from conventional wrought iron; the ship's single four-bladed propeller was made of steel to withstand strikes by hard chunks of ice.
The icebreaker's two-cylinder compound steam engine was the single most expensive component on the ship, costing over 16,000 guilders. The engine comprised a high-speed cylinder and a low-speed cylinder, fed by a Scotch boiler costing another 7,882 guilders. There were two fireboxes in the boiler, with the process of generating sufficient steam pressure to sail taking two days.
Internally, the cabin was luxuriously outfitted with mahogany panelling, reflecting the ship's intended role in ferrying Rijkswaterstaat directors around the country during the warmer months of the year when she would not be breaking ice; elsewhere aboard, the panelling was of painted pine. Since the crew of six would be required to live on the ship around the clock during icebreaking operations, the vessel was fitted with steam heating throughout, with additional stoves for heating in most compartments. Three heads with flush toilet systems and urinals were also fitted.
Although the Minister of Public Works, Trade and Industry approved naming the new icebreaker after Christiaan Brunings (1736-1805), the famous hydraulic engineer recognised as the founder of the Rijkswaterstaat, bureaucratic delays led to the ship being launched in 1900 with the mundane name De Ijsbreker (The Icebreaker). This was remedied shortly thereafter when the name Christiaan Brunings was formally given to the vessel. Christiaan Brunings sailed from her home port of Dordrecht in the winter of 1901 and immediately commenced icebreaking operations. Two of the coldest winters recorded during the 20th century in the Netherlands were in 1917 and 1929, when Christiaan Brunings was kept busy breaking up frozen rivers and canals.
The ship also saw military service during the First World War, being used as a coastal patrol vessel from the summer of 1915 and, later, as a supply ship before being returned to the Rijkswaterstaat in 1919. During the Second World War, Christiaan Brunings was largely docked at Maassluis, west of Rotterdam, until late 1944, when the German military began requisitioning steam and motor vessels. Christiaan Brunings and many other vessels were secreted away in a branch of the River Meuse, near Heenvliet, but in January 1945 the icebreaker was heavily damaged in a British air raid and almost sank. Repaired at a cost of 8,000 guilders, Christiaan Brunings returned to government service after the war, though was no longer used for icebreaking.
Given her cumbersome nature and unsuitable furnishings, Christiaan Brunings was not used as an executive vessel after the Second World War. With the ship now operated by the Research Service for Estuaries, Maritime Rivers, and Coasts, the original cabin was replaced with the current cabin in 1951 to better suit the ship for her role as a sounding vessel, taking measurements of water depth. In February 1953, while evacuating victims of the massive flooding in the Netherlands, Christiaan Brunings ran aground on a large sandbar between Stellendam and Hellevoetsluis; she returned to service a week later and, on 11 February, carried Queen Juliana to Zierikzee (in the southwest Netherlands) to view the flood disaster area. The vessel remained in the area until mid-March, taking soundings as part of the post-flood repair efforts. Thereafter, Christiaan Brunings was used over the next 13 years to collect data on river and tidal flows, fresh water/salt water boundaries, silt deposition, sandbars, and ice transport.
In 1966, the Dutch government solicited the National Maritime Museum's interest in receiving the Christiaan Brunings after she was decommissioned from service, a move which would save her from the scrapyard. With financial assistance from several large Dutch shipyards, the sale was finalised in 1968 and Christiaan Brunings joined the museum's collection.

Christiaan Brunings was designed with a hinged funnel to permit the vessel to pass under low bridges on Dutch inland waterways and canals. Given the many fixed bridges in the Netherlands with limited clearance, steam vessels operating on rivers and canals were often designed with such hinged or telescopic funnels. |

In 2024, the National Maritime Museum began experimenting with other, more sustainable fuels. |
